A Wireless Low Power and Lossy Networks (LLNs) is a network of embedded devices, such as sensors, that have limited power, memory, and processing capability. The growing importance of wireless LLN becomes apparent when you look at how LLN networks will be used. Applications include the Internet of Things (IoT), Smart Grid, Machine to Machine (M2M) communications, and vehicular information systems. In other words, the number of devices that connect these networks will be in the tens of billions. This course examines the key network protocols designed to operate in low power and lossy environment. Protocols covered include, IEEE 802.15.4, Bluetooth Low Energy, ZigBee, 6LoWPAN, RPL, WirelessHart, ISA100, and LoRaWAN. This course is a 2-day course on LLN, as part of the Wireless Course offerings at CellStream. This class is ideal for anyone looking for skills and knowledge on wireless LLNs or needing to understand the technologies that are enabling the Internet of Things (IoT). See the course details here.

The IEEE 802.15.4 is the dominant wireless standard for sensor products and networks that are being deployed in homes, industrial environments, and utility networks. It is the wireless technology that underlies most sensor networks, including ZigBee, ISA-100 Wireless, WirelessHART, and Wi-SUN.
This course details the 802.15.4-2003 and 2006 MAC and PHY. It compares and contrasts the operational differences between a beacon-enabled network and a non-beacon enabled network. The course also cover the 802.15.4e,g enhancements, which extend the 802.15.4 PHY and MAC specification to meet the industrial control and smart metering application requirements. While ZigBee is based on the earlier 802.15.4 specifications, these enhancements provide the base on which the WirelessHART, ISA100-wireless, and WiSUN specifications are built.

ZigBee is a set of specifications that define how small low power devices communicate. It is a leading standard for the connectivity of wireless sensors, control and monitoring networks for home and industrial automation. Applications include controlling light switches, patient monitoring, smart energy, and traffic management systems.
ZigBee builds on the IEEE 802.15.4 Wireless Personal Area Network (WPAN) standard, adding network and application layers, as well as application objects and cluster libraries that allow vendors to customize their solution. This course takes a layered approach to explaining how ZigBee networks work. It starts with a detailed explanation of the 802.15.4 physical and MAC layers. It then takes the student through the evolution of ZigBee network layer, covering ZigBee 2007, ZigBee PRO, and ZigBee IP. See the course details here.

The course begins with an explanation of the different standards activities focused on vehicular communications. The technology is also known as Dedicated Short Range Communications (DSRC). The course then focuses one of the most important standards; the IEEE 802.11p and the IEEE 1609 standards for Wireless Access in Vehicular Environments (WAVE).
IEEE 802.11p WAVE is an amendment to the 802.11 standards to support wireless communications in a high speed vehicular environment. IEEE 1609 WAVE provides the higher layer standards to support fast reliable messaging over an 802.11p wireless network, supporting applications such as electronic toll payments, the broadcast of safety and traffic information, and vehicle-to-vehicle (V2V) communications.
This class is ideal for anyone looking for skills and knowledge on WAVE or needing to understand the technologies that are enabling the Internet of Things (IoT). See the course details here.

This course examines the work being undertaken by the IEEE Project 802.11 standards working group to evolve the Wi-Fi technologies to support the Internet of Things (IoT). In particular it will look at the technologies and mechanisms defined in the 802.11ah sub 1 GHz, 802.11ay Next Generation 60 GHz (NG60), 802.11ax High Efficiency WLAN (HEW), 802.11az Next Generation Positioning (NGP) amendments. This class is ideal for anyone looking to understand how the next generation of Wi-Fi networks will support ultra-dense IoT deployments, cell ranges of up to 1 km, and data rates up to 20 Gbps. This course also looks at the enhancements being made to improve the energy efficiency and the location accuracy of Wi-Fi networks. See the course details here.
